Within the UK, the "Long Term Athlete Development" (LTAD) model has been proposed by a variety of national governing bodies to offer a first step to considering the approach to talent development. The model, which is primarily a physiological perspective, presents an advancement of understanding of developing athletic potential alongside biological growth. It focuses on training to optimize performance longitudinally, and considers sensitive developmental periods known as "windows of opportunity". However, it appears that there are a number of problems with this theoretical model that are not necessarily transparent to coaches. Principally, the model is only one-dimensional, there is a lack of empirical evidence upon which the model is based, and interpretations of the model are restricted because the data on which it is based rely on questionable assumptions and erroneous methodologies. Fundamentally, this is a generic model rather than an individualized plan for athletes. It is crucial that the LTAD model is seen as a "work in progress" and the challenge, particularly for paediatric exercise scientists, is to question, test, and revise the model. It is unlikely that this can be accomplished using classical experimental research methodology but this should not deter practitioners from acquiring valid and reliable evidence.  相似文献   

Assessing Outcomes: Practical Methods and Evidence          下载免费PDF全文

University counseling center clients’ (N = 52) perceptions of precounseling functioning were highly correlated with their actual well‐being scores at intake. The magnitude of change based on perceptions of precounseling functioning to current well‐being was approximately double of what is found from the difference of actual precounseling well‐being to current well‐being scores. Retrospective methods for assessing precounseling functioning are best suited for comparison among clients or counseling processes.  相似文献

Investigating ambivalence towards organisational change in a Football Championship Subdivision intercollegiate athletic department     

Jon Welty Peachey  Jennifer Bruening 《Sport Management Review》2012,15(2):171-186

To date, few scholars have examined organisational change in the sport industry, with the majority focusing on forces driving change. Only a handful have investigated responses to change, primarily centering upon factors contributing to resistance. Historically, most work in measuring attitudes has placed them on a bipolar continuum ranging from negative to positive. Recently, though, researchers have presented data to support an indifference-ambivalence attitudinal dimension characterised by evaluative tension. There have been few studies, however, that have examined ambivalence towards organisational change. Therefore, this research was undertaken to investigate ambivalence towards organisational change in a Football Championship Subdivision intercollegiate athletic department in the U.S. Through a case study, we demonstrate that ambivalence was a salient response to change, and that intrapersonal conflict, perceived lack of institutional support, managerial turnover, and previous negative experience with change served as antecedents. We then highlight the theoretical and practical significance of our study.  相似文献   

Extending the Conversation on Visions of Jewish Education: The Danger of Recipes     

Jon A. Levisohn 《Journal of Jewish Education》2013,79(3):319-323

This articles extends the conversation begun by Levisohn in volume 71:1 of this journal, and continued by a number of respondents in volume 71:2. These articles identify two notable themes among the responses: The first is the issue of pluralism, and the tension between vision and exclusion. Despite the best of intentions, it seems unavoidable that vision-driven institutions must necessarily exclude certain ideas, certain practices, and most painfully, certain people; standing for something must always mean not standing for everything. Second, several respondents are concerned in one way or another with the very nature of an educational vision. Particularly, the question arises whether the construction of a vision around the key question, “What is an educated Jew?”, is limiting, either intellectually or practically. Beyond discussing these two themes, the article extends the conversation about vision in Jewish education by raising a concern, which the author attributes to Franz Rosenzweig, about the way in which a commitment to organizing institutions according to vision may obscure the fundamental need for openness and spontaneity in educational arrangements.  相似文献   

Student‐teachers' perspectives on positive and negative social processes in school     

Suzanne Graham  Jon Roberts 《Teachers and Teaching》2013,19(4):399-410

In recent years, the Standards for Qualified Teacher Status in England have placed new emphasis on student‐teachers' ability to become integrated into the ‘corporate life of the school’ and to work with other professionals. Little research, however, has been carried out into how student‐teachers perceive the social processes and interactions that are central to such integration during their initial teacher education school placements. This study aims to shed light on these perceptions. The data, gathered from 23 student‐teachers through interviews and reflective writing, illustrate the extent to which the participants perceived such social processes as supporting or obstructing their development as teachers. Signals of inclusion, the degree of match or mismatch in students' and school colleagues' role expectations, and the social awareness of both school and student‐teacher emerged as crucial factors in this respect. The student‐teachers' accounts show their social interactions with school staff to be meaningful in developing their ‘teacher self’ and to be profoundly emotionally charged. The implications for mentor and student‐teacher role preparation are discussed in this article.  相似文献

University Students as Creators of Personal Knowledge: an alternative epistemological view     

Jon Nixon 《Teaching in Higher Education》2013,18(3):277-298

Abstract

This paper takes the form of a position statement followed by three responses from colleagues located in different institutions of higher education. The resulting colloquium is concerned, among other things, with the role of the academic within higher education and with the notion of freedom as it relates to the definition and development of that role. It sets itself against the traditional notion of ‘academic freedom’ and explores alternative constructions of academic professionalism. Freedom remains central to these constructions; but an outward‐looking emancipatory notion of freedom, not an inward‐looking and self‐interested notion. The practices that are documented in the paper and the issues that these raise are a direct consequence of this preoccupation with reconstructing the moral bases of academic professionalism. The paper reaches no firm conclusions, but highlights a number of key differences within a shared emancipatory project: differences shaped by the institutional and cultural contexts of higher education and, in particular, by the gendering of the academic workplace; differences inscribed in the conditions and divisions of labour within higher education and, more specifically, in the organisational structures of support for professional growth and development; differences of value and purpose that help determine what, for each of the authors, it means to be an academic. The form of the paper, with its emphasis on the examined life as deliberative and public, reflects this preoccupation with achieving principled agreement through the recognition and exploration of difference.  相似文献   

Information retrieval in the workplace: A comparison of professional search practices     

Tony Russell-Rose  Jon Chamberlain  Leif Azzopardi 《Information processing & management》2018,54(6):1042-1057

Legal researchers, recruitment professionals, healthcare information professionals, and patent analysts all undertake work tasks where search forms a core part of their duties. In these instances, the search task is often complex and time-consuming and requires specialist expertise to identify relevant documents and insights within large domain-specific repositories and collections. Several studies have been made investigating the search practices of professionals such as these, but few have attempted to directly compare their professional practices and so it remains unclear to what extent insights and approaches from one domain can be applied to another. In this paper we describe the results of a survey of a purposive sample of 108 legal researchers, 64 recruitment professionals and 107 healthcare information professionals. Their responses are compared with results from a previous survey of 81 patent analysts. The survey investigated their search practices and preferences, the types of functionality they value, and their requirements for future information retrieval systems. The results reveal that these professions share many fundamental needs and face similar challenges. In particular a continuing preference to formulate queries as Boolean expressions, the need to manage, organise and re-use search strategies and results and an ambivalence toward the use of relevance ranking. The results stress the importance of recall and coverage for the healthcare and patent professionals, while precision and recency were more important to the legal and recruitment professionals. The results also highlight the need to ensure that search systems give confidence to the professional searcher and so trust, explainability and accountability remains a significant challenge when developing such systems. The findings suggest that translational research between the different areas could benefit professionals across domains.  相似文献
